I transfered a lvl 60 toon to test it. Keep in mind, this is what the UI said, they never actually boosted the toon so I can't tell you how it will end up working.

well it was something along of those lines i where looking for. so no worries
guessing we are getting some more information on this at some point
i guess we can safely assume that "veteran" bonus is gonna go live as it would encourge folks to level abit by hand.

It'd be a bit shit if you had no gold - especially as I have heard nothing about riding training being tied in. It would be a bit poor if you didn't at least have 150 skill upon boosting.

You get free riding until 280% for free.

I tested on PTR with a character with no riding skill. This is exactly what happens.

All your gear, bags, and inventory are removed and mailed to you. Your bags are replaced by 4 embersilk bags. You automatically have riding upgraded to 300 for free. You are given 150 gold, food, 483 gear that is equipped to your character and you are dropped off in your respective faction's area on timeless isle. Your heartstone is set to the vale. You are taught every flight path in the game, all the maps on Azeroth and Outland are marked as "discovered."

The game checks if you are level 60. If you are, then the game checks if you have any professions + first aid. It will boost what you have to 600. If you never learned first aid, but have level 1 JC and Enchanting, it will give you a boost to JC and Enchanting and your first aid will remain unlearned. This is also the case if you only have 1 primary profession learned just as only JC, and nothing else. Your JC will be 600, and thats it.

While you are given free 300 riding, I do not think you are given a free mount, which is a bit of an oversight on their part (In case a brand brand brand new player joins the game, pays for everything including WoD, and have to go back to azeroth in order to buy a mount).

Other than that, you get nothing else. Im pretty sure the rest Exp bar carries over in the boost, but only if you apply the boost while the level cap has been raised and we can get exp (WoD launch date). This means if you have a level 60 character, park it in a city. If you want to level it, at launch boost it to 90, the full 2 levels of 200% rested exp will carry over at 90.

Before you park the char, make sure you are at as close to 61 as possible, if the exp bar carries over and you are at 60,99 before the boost, you should be 90,99 after the boost.
